Is Blackfire Profiler safe?

Clean risk

Blackfire Profiler captures active-tab URLs, headers, IPs, and request bodies when the user starts a recording.

When a user starts a Blackfire recording, the extension attaches webRequest listeners to the selected tab and records request URLs, request and response headers, IP addresses, and request bodies. The captured request details are kept for the extension's recorder/profiling display rather than being tied to an evidenced external endpoint in the reviewed claim.
